海上风电钢管混凝土导管架荷载-结构耦合动力响应分析
Coupled Load-Structure Dynamic Response of Offshore Wind Power Concrete-Filled Steel Tubular Jackets
导管架支撑结构作为过渡水深海域(30~60 m)海上风电开发的主流基础形式,虽较单桩基础具有更优的结构刚度,但存在建造成本偏高的问题。本文提出一种钢管混凝土组合结构优化方案:通过对导管架角柱采用全截面填充混凝土,充分发挥钢-混凝土组合结构的材料协同作用,在保证结构刚度的前提下优化钢管壁厚,钢材整体用量可降低17.3%。首先建立角柱填充混凝土前后的有限元数值模型,对角柱填充混凝土后KK节点的承载力进行校核。结果表明,相较于传统纯钢结构,角柱填充混凝土后KK节点的承载力大幅提升。在此基础上,构建导管架海上风电支撑结构荷载-结构耦合数值计算模型,针对机组正常运行与极限停机两类工况开展时域耦合动力响应模拟。研究结果表明:正常运行工况下,相较于纯钢结构,钢管混凝土导管架的塔顶位移、基础纵荡与纵摇运动幅值均有所减小,仅机舱加速度略有增大;结构整体荷载响应波动幅度降低,抗疲劳性能更优。在极限工况下,钢管混凝土结构的动力响应与所受荷载均显著低于纯钢结构的动力响应与所受荷载,其结构安全储备更高。
Jacket support structures are a predominant foundation form for offshore wind power development in transitional water depths (30-60 m). Although they provide superior structural stiffness compared to monopile foundations, their construction costs remain relatively high. This study proposes an optimized concrete-filled steel tube (CFST) composite structural solution. By implementing full-section concrete filling in the jacket corner columns, the material synergy effect of steel-concrete composite structures is fully exploited, achieving optimized steel wall thickness (17.3% reduction in steel consumption) while maintaining structural stiffness. Firstly, finite element numerical analysis models with and without concrete-filled corner columns were established to verify the bearing capacity of KK joints after concrete filling. The results show that the bearing capacity is greatly improved compared with traditional pure steel structures after concrete filling in the corner columns. Subsequently, a coupled load-structure numerical model for jacket-supported offshore wind turbines was developed to conduct time-domain coupled dynamic response simulations under both normal operation and extreme shutdown conditions. The results show that under normal operating conditions, the CFST jacket support structure exhibits reduced tower top displacement, foundation surge, and pitch motions compared to conventional steel structures, albeit with a slight increase in nacelle acceleration. The overall load response fluctuation amplitude decreases significantly, indicating improved fatigue resistance. Under extreme conditions, both dynamic responses and loads of the CFST structure are notably lower than those of the pure steel structure, indicating higher structural safety.
